Bubs agreed on the SRP but i was just trying to give some examples and not just look like a megs tart (which of course i am). i would say though that the SRP is very good if you have a car with deep scratches that simply will not come out with a normal polish. the fillers in it do a fantastic job of covering up the scratches. Oh and i would never just stop at the polish. for long lasting shine you really do need a decent wax (either liquid like the megs gold class/ stage 3 or a solid one like dodo juice etc) or a sealant. I find most sealants last a bit longer but are, as you say synthetic based.

Very nice! These cars look really nice in that colour :)
